1. How do you know the man will do the two things you say they always do. I never have. My orgasm is trivial compared to a woman's which I delight in. See quotation by Twain on candles and candlesticks
2. Lordotic sex (a 50 cent word for sex from behind_ is the normal mammalian sexual position. Evolution probably had a say in this.
3. Lordotic ssx allows the male to inhale both the vaginal and anal pheromones, very satiisfying. Plus the view is wonderful. My lovers all touch their clits with lordotic sex, leading to excellent orgasms.
None of this detract from missionary style but think for a moment about the origins of this term. Sex is not an either/or - done well, my love has already had multiple orgasms with foreplay, especially 69 for a long time. Missionary allows the intimacy to delve into another's soul. How wonderful.
